In order to understand the effects of rapeseed planting as green manure on the growth and yield of rice cultivar ‘Qing xiang ruan geng’, a rapeseed cultivar ‘Huyou21’ were used as green manure returning to field at flowering stage. The results showed that the rice plant height and chlorophyll content increased under the treatment of rapeseed returning as green fertilizer, and also increased under 20% fertilizer reduction after rapeseed returning to field. With the amount of rapeseed returning increased, the rice yield and the yield-component traits including grains per panicle and productive panicles number increased, while the 1000-grain weight deceased, but there was no statistical difference. In addition, when the rapeseed returning amount was 22.5 t/hm², the rice yield was increased significantly, and also increased under that condition with 20% fertilizer reduction.
